Abstract: A system and method is disclosed for adapting a continuous presence videoconferencing layout according to interactions between conferees. Using regions of interest found in video images, the arrangement of images of conferees may be dynamically arranged as displayed by endpoints. Arrangements may be responsive to various metrics, including the position of conferees in a room and dominant conferees in the videoconference. Video images may be manipulated as part of the arrangement, including cropping and mirroring the video image. As interactions between conferees change, the layout may be automatically rearranged responsive to the changed interactions.

Abstract: A media relay conferencing system includes a media relay multipoint control unit and a media relay endpoint that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that media relay videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring media relay endpoint requests an Intra frame for a video stream received from a presenting media relay endpoint, a media relay multipoint control unit may respond by requesting the presenting media relay endpoint to synchronize a reference frame in an encoder of the presenting media relay endpoint, which encodes the relevant relay compressed video stream, with a reference frame in a decoder of the requiring media relay endpoint.
